Question about Sony Ericsson K850i Mobile Phone

My Sony Ericsson K850i is unusable

Hi there,

My K850i has started to turn off its screen for no reason. It started when I would write a text message but now its happening al the time. It seems to work fine but the screen just switches off and I have to wait until the LED's go off until I can use it again, and then it will be fine for a few seconds before it happens again which makes it completely un usable. It works fine if someone phones me. Its so frustraiting. I have installed the latest update but that has not resolved the problem.

any ideas?
Kevin

Check first if there is oxide on ac charger contacts , at the base of the phone, it is a common problem with this model. Oxide in there cause a short and phone goes off.

If there is no oxide, then it is an internal fault, probably a bad LCD ribbon cable, or a short on one of the buttons.

The unit must be taken apart by a technician to find out the fault.

Restore the phone to original settings, hard reset or wipe it out.
that should restore the settings and it shouldn't turn the display off constantly.

When I am writing a text message the phone starts predicting words. I just want to send a simple email without any ''help''


Hi!

If you are seeing the T9 icon on your screen, this is the T9 Text input feature of your phone. It act's like a built-in dictionary for commonly used in a sentence.

To disable this, while on writing mode, press and hold * key to disable text input.
